Structure and Properties of Peptides The peptide bond in proteins is only found between proline residues usually trans unless proline is the next amino acid usually cis unless proline is the next amino acid is planar because of steric hinderance only found between proline residues usually trans unless proline is the next amino acid usually cis unless proline is the next amino acid is planar because of steric hinderance ANSWER DOWNLOAD EXAMIANS APP
Structure and Properties of Peptides The Ramachandran Plot illustrates the fact that the F & Y angles can assume only a single value in a protein the peptide bond is planar the F & Y angles can assume any value in a peptide the F & Y angles can assume approximately three different values the F & Y angles can assume only a single value in a protein the peptide bond is planar the F & Y angles can assume any value in a peptide the F & Y angles can assume approximately three different values ANSWER DOWNLOAD EXAMIANS APP
